The Department of Agriculture reports 
that the introduction of hard winter wheat 
from Kussia into Kansas and other states of 
the central Great Plains area in the early 
seventies was an epoch-making event. The 
growing of' these Crimean wheats, especially 
the Turkey and Kharkov varieties, has been 
the principal cause of the prosperous develop- 
ment of much of that section. The develop- 
ment and distribution of Kanred, an im- 
proved strain of hard red winter wheat, may 
prove equally epoch-making in the history of 
Kansas. Kanred is one of the most impor- 
tant examples of the improvement of wheat 
by the method of pure line selection. It is 
the product of a single head, selected in 1906 
at the Kansas Agricultural Experiment Sta- 
tion. Its true value was determined only 
after many years of careful experiments, but 
as a reward not fewer than 500,000 acres were 
sown in the State of Kansas alone in the 
fall of 1919. Since 1917, Kanred has been 
under experiment in many states other than 
Kansas. Last fall many thousands of bushels 
were introduced into other states for com- 
mercial growing. Kanred is unusually well 
adapted to many of the varying conditions in 
the state of Kansas. Its principal advantage 
over Turkey and Kharkov is its resistance to 
some forms of bo'th stem rust and leaf rust. 
It "has other advantages, however, such as 
slightly greater winter hardiness, earlier ma- 
turity, and makes better pasture. Those fac^._ 
tors have caused it to outyield the Turkey 
and Kharkov wheats in most sections of 
Kansas by 3 to 5 bushels per acre. The same 
factors may or may not be as important in 
other states. 

. To determine the varieties of Australian 
wheat best adapted to conditions on the 
Pacific coast, the United States Department 
of Agriculture has conducted a series of ex- 
periments which accurately ascertained the 
yield and quality of those varieties already 
of commercial importance in that region, as 
well as other varieties, samples of which were 
brought direct from Australia. In connection 
with the latter phase of the investigation 
more than 130 samples of wheat were ob- 
tained, representing 92 distinct varieties. 
Kesults from the early experiments with these 
wheats show that the "Federation group," 
consisting of three varieties, Federation, Hard 
Federation, and White Federation, is prob- 
ably the best suited to this western region. 
These three varieties were compared in 
yield with the leading commercial wheats, in- 
cluding the Bluestem, Australian varieties, 
Pacific, White Australian, and Early Baart, 
and produced higher yields, according to the 
department's cereal specialists. Hard Feder- 
ation produced the larger yields in Oregon, 
while White Federation did better in Cali- 
fornia. Milling experiments indicate that 
Hard Federation is equal or superior for mill- 
ing and bread-making purposes to the leading 
commercial varieties now grown on the Pacific 
coast and also superior in this regard to Fed- 
eration and White Federation.
